I was recently testing Infrastructure as a Service (IaaS) through Terraform.
To be able to get a basic understanding of Terraform, I followed instructions in a book called Learning DevOps to try out a simple test they had outlined in the book.

I found the test to be quite interesting, so I want to share the link to which the book had also instructed to go to look.

First i had to install Terraform onto the PC.
During the test, I did have some trouble with naming conflicts and having to figure out some authentication mishaps, but after those were resolved it worked as intended.
Here is a picture i made of the setup
The Terraform script in the test creates various resources in Azure, e.g. VM (Virtual Machine) that is accessible from the internet.
There is actually a nice tool in Azure that lets one see the connections/dependencies of different resources. It’s called Resource Visualizer
A picture of the view Resource Visualizer showed me
The test’s execution was quite straightforward. I essentially just used the following four commands:
terraform init
terraform plan -out=terraform-run4.tfstate
terraform apply “terraform-run4.tfstate”
terraform destroy
In the future I have intentions of replicating a similar test to this one with Azure DevOps and Terraform.
